Well my head gaskets have went and now I gotta fork out the dough for repair. I'm still waitin' on my mechanic to get me a finished quote. My question is regarding the machining. My mechanic says that if I want any sort of a warrenty on their work, they need to machine the heads to ensure they will be able to match up with the gaskets smoothly. However, I know this is gonna cost more in terms of labour as well as sending them off to be repaired or whatever. What will this cost me? I'm considering buying a brand new pair or refurbished heads that have all new seals as well as having been shaven and all cleaned up and they could be mine for $205 US. Is it worth it to do this? I'm a believer of symmetry so I figure I should get both but I do have the option of getting just one rebuilt head. Another thing is would they machine both heads if they are replacing both gaskets? Thanks for anyone who can help
